UNITED STATES PATENT OFFICE WILLIAM OOTHOUT, OF BROOKLYN, E. D., NEWYORK, ASSIGNOR TO HIMSELF AND GIBBONS L. KELTY, OF SAME PLACE.

IMPROVEMENT IN WARP-REGULATORS.

Specification forming part of Letters Patent No. 189,775., dated April17, 1877 application tiled February 14,1877.

' which the, following is a specification In looms for weaving cordedfabrics. such as terry, and piled fabrics, such as Brussels, Velvets,860.,13116 surface-warp is drawn along more rapidly than thefoundation-or back warps, and in so doing there is sometimesirregularity in'consequence of the varying tension or friction upon theyarn or yarnbeams; hence the corded surface is liable to slightirregularities, or a greater or less proportion of surface-warp incomparison to the.

foundation-warpis consumed. I

The object of the present invention is to insure entire uniformity inthe surface-Warp relatively to the foundation or back warps and for thispurpose I make use of two sets of regulator-rollers, one for thesurface-warps, and the other for the back or foundation warps, and theseare geared together in such a manner that the surface speed of one setof rollers will bear the same relation .to the surface speed of theother set of rollers that the surface-warps bear to the foundationorback warps, so that while the take-up operates in the usual way to drawalong the fabric in the process of weaving, the warp-regulatorwillinsure uniformity in the supply of the different 'kinds of warps.

1n the drawing I have represented the improvement by a sectiontransversely of the regulator-rollers.

The cloth beam a, breast beam b,1ay c, heddles d and their operativemechanisms are to be of any desired character, and operate in any of thewell-known modes of weaving, and, hence, do not require furtherexplanation.

The rollers f g h form the group of rollers that regulate the back orfoundation warps 70.

These are geared together, and the warps pass around the same in themanner indicated, so that they move together, and the movement 'of thesurface of the rollers determines the speed of the warps.

I am aware that one group of rollers of this character has been employedto regulate the whole of the warps in the loom.

The rollers l m n, form a second group of warp-regulating rollers forthe surface-warps 8. These rollers are geared together, so that theymove with the warps, and at the same surface speed.

' I have shown the gears 0 upon the rollersf, g, and h larger than thegears 4' upon the rollers l m 'n, so that the gears can all form one Itrain, and the respective groups of rollers will move at the relativespeed resulting from the difference in the size of the gears. It maysometimes be preferable to have the rollers of each group gearedtogether, and to have changeable gears upon the projecting shafts of oneroller in each group to connect the groups, so that these gears can bevaried to proportion the surface speed of the respective groups ofrollers according to the relative speed with which the surface andfoundation warps are required for the weaving.

I claim as myinvention- In a warp-regulator, the combination of twogroups of rollers, one for the surface-warps, and the other for thefoundation or back warps, and differential gearing for connecting therollers and determining the relative speeds of movement of the warps,substantially as set forth.

Signed by me this 8th day of February, A. D. 1877.
